が特１こ重要である。Generally, a printing device using an ink-on-demand type ink shed head is a non-impact type, and therefore generates little noise. In addition, it is not necessary to use special thermal paper as the object to be printed, and it is not necessary to use plain paper. This ink is deposited in dots, and printing can be performed using a combination of these dots. In addition, the overall structure of the printing device is simple and compact, the printing speed is fast, and the printing energy is small. Furthermore, by using a nozzle with a finer hole diameter, it is possible to increase the density of τ dots. High quality printing is possible and printing quality can be improved. In addition, the hole diameter of the nozzle is 30 to 20 (11
It is especially important that the nozzle holes have good printing characteristics and that the nozzle holes are precisely formed in a predetermined shape.

実状である。However, since the nozzle hole is extremely small with a diameter of about 30 to 2 Even in the case where the nozzle hole is constructed, drilling the nozzle hole with high precision is a very difficult task. A method for forming such a nozzle hole is to make a hole in a metal material with a fine drill, or to erode a metal material, glass material, etc. into a predetermined shape using photo-etching means, thereby forming a groove to serve as the nozzle hole. It is also conceivable to form a nozzle hole by pasting a plate material to the top to serve as a lid. However, drilling holes with an extremely thin drill makes it difficult to maintain hole diameter accuracy (usually less than ±2μ) during mass production, and when trenches are excavated (formed) by photoetching, minute irregularities are formed on the inner wall surface between the cores. Moreover, the corner part is gentle 1
This may be etched and not formed sharply, or the adhesive used to attach the plate material that will become the lid may flow into the nozzle hole and change the shape of the nozzle hole, or the amount of adhesive used may be insufficient. In this case, adjacent grooves are connected,
In many cases, it becomes useless as an inkjet head. Furthermore, when bonding plate materials with glass, a similar situation occurs when adhesive is used. It cannot be said that a method for manufacturing an inkjet head having such fine nozzle holes with high precision and high print quality simply and with high yield has yet been established. Therefore, the reality is that an in-jet head with ideal printing quality has not been obtained.

However, when manufactured in this way, the overall size is 15 to 25% smaller than before firing, and there is no leakage between the ink grooves. Of course, almost no deformation of the cross-sectional shape of the ink groove or nozzle hole was observed, and an ink head capable of depositing dots with a predetermined clear shape could be manufactured.

。As described above, the first aspect of the present invention is that a ceramic green sheet + a predetermined shape are pressure-molded and then fired, so an inkjet head with precise pressure chambers, ink grooves, nozzle holes, etc. can be created. The ceramic body that constitutes the inkjet head is extremely easy to manufacture, and can maintain stable nozzle characteristics over a long period of time due to the abrasion resistance and corrosion resistance of the ceramic body after firing. By utilizing the excellent insulating properties of , and by printing a conductive pattern on the fired piece, the head itself can be made into a printed circuit board, and an electronic circuit can be formed using the printed circuit board number. It is possible to pack it into one compact unit. Furthermore, since a binary thermal resistor pattern can be embedded in the ceramic body that forms the head, it is possible to easily maintain a constant temperature, which is a major factor that affects the ink ejection condition. It is possible to provide an inkjet head with many excellent characteristics such as.
